I remember the discussion - but the claim a draw text seems seems not be
accepted by Arena, the opponent makes a moves and it is sent to Crafty. At this
point Crafty thinks it has already claimed draw and it never responds to the
last move sent and then loses on time. For each pf the 3 draw claims, I jsut
addded code that restored the old way by adding an "arena" qualifier"
"MakeMove(tree, MAXPLY, last_pv.path[1], wtm);
tree->rep_list[++tree->rep_game] = HashKey;
if (RepetitionDraw(tree) == 1&& !arena_uci && !xboard) {
^
|
Print(128, "%sI claim a draw by 3-fold repetition after my move.%s\n",
Reverse(), Normal());
if (xboard)
Print(4095, "1/2-1/2 {Drawn by 3-fold repetition}\n");
value = DrawScore(wtm);
}
"
Arena seems to be ok with the old method - but maybe I have just not notice any
exceptions.
